HUMIDIFYING DEVICE FOR INTERNAL COMBUSTION ENGINES Original Filed May 25, 1927 Patented Dec. 17, 1929 UNITED STATES PATENT OFFICE JOHN ARGHIBALD BELL, OF MONTREAL, QUEBEC, OANADA, ASSIGNOB OF ONE-HALF TO LAWRENCE MCMILLEN MONAUGHTON, OF MONTREAL, CANADA HUMIDIFYING DEVICE FOR INTERNAL-COMBUSTION ENGINES Application filed May 23, 1927, Serial The invention relates to a humidifying de vice for internal combustion engines, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel features of construction pointed out broadly and specifically in the claim'for novelty following a description containing an ex planation in detail of an acceptable form of the invention.

The objects of the invention are to eliminate the formation of carbon in gasoline and oil engines and to disintegrate any carbon that may possibly accumulate or be accumulated in any engine cylinder; to intensify the effect of each explosion and thereby gain power and efliciency throughout; to insure a degree of humidity that will modify the indrawn air and materially increase the engine speed as well as improve and smooth the operation thereof; to augment the expansible properties of the exploded gases; to economize in the consumption of fuel and break up'the particles effectively thus insuring a smoother and more powerful mixture and generally to provide an auxiliary device in explosion engines that will affect their running conditions for their betterment, and at the same time be cheap to produce and add no cost in the operation.

In the drawings, Figure 1 is a perspective view of the device showing its connections to parts of an internal combustion engine.

Figure 2 is an enlarged vertical section of the generator and feeder.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, the numeral 5 indicates a casing containing the superheater chamber 6 having a steam outlet 7 and a steam inlet 8 from a flash chamber 9 the latter being immediately over an externally threaded hot point 10 adapted to be screwed into and through the exhaust manifold casing 11 and to maintain the floor of p the flash chamber 9 at a very high temperature sufliciently so to flash the incoming water through the inlet 12 into steam.

The inlet 8 into the superheating chamber No. 193,560. Renewed May 13, 1929.

6 is formed with a ball valve seat 13 which encircles the said inlet port to which the outlet passage 14 leads from the flash chamber 9, thereby affording a ready egress for the steam generated into the superheating chamber 6, where it is thoroughly dried and emitted through the steam outlet.

The chamber 6 is slightly contracted at its lower end and forms a valve chamber 15 containing the ball valve 16 resting on the seat 13, from which it is drawn by the suction of the engine.

The casing 5 at its upper end is internally threaded at 17 within the chamber 6 and the dome top 18 through its threaded stopper extension 19 is screwed into the thread 17, this stopper 19 having a recess 20- for the spring 21 and pressing said spring on the ball valve 16 within the valve chamber 15 and maintaining said valve on its seat, except during the operation when it is subject to intermittent movements due to the suction resulting from the piston motions in the cylinder.

The water inlet 12 is internally threaded and the steam connection 22 is screwed thereinto and the tube 23 inserted in said connection and suitably packed, this tube 23 extending from the water jacket 24 of an engine cylinder or any other source of supply con- Veniently situated in relation to the exhaust manifold.

The steam outlet 7 is internally threaded and a steam connection 25 screwed thereinto and the tube 26 is inserted in said connection 25 and suitably packed.

The tube 26 extends from said outlet 7 to the intake manifold 27 of the engine thereby forming the passage for the conveyance of the steam generated in the flash chamber 9 and dried in the superheating chamber 6 to the several cylinders of the engine.

In brief in the operation of this invention, the water trickles drop bydrop into the flash chamber 9, the feed being regulated by the operated valve 28, meanwhile the hot exloded gases in the manifold heat the hot point 10, which in turn conveys the heat to the metal of the floor of said chamber 9. This floor is so hot that the water flashes into steam and at each suction stroke of the several pistons the ball valve rises to admit the generated steam into the superheating chamber from which it is discharged to the intake manifold and so distributed to the Working cylinders as required and disseminated through the charge before and after the ingress of said charge to the cylinder.

v What I claim is I In a humidifying device for internal coin: bustion engines, a casing having a threaded boss at the bottom thereof, a lateral bore thereabove, the lower surface of said bore forming a flash surface immediately over 7 said boss, a Vertical bore in communication 7 W1th said lateral bore, sa1d vertical bore being contracted at its lower end to form a seal and Valve chamber, a ball valve in sald chamber engaging said seat, a spring engag ng sald ball valve, the other end of said spring being secured Within a dome forming a cover for said casing, said Vertical bore being connected to the, intake manifold of the engine and said lateral bore being connected to a source of Water supply adapted to trickle slowly on to said flash surface.
